As I can see in ML Linux there is currently at least one platform using such mode: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm64/boot/dts/xilinx/versal-net.dtsi#n1010 In our case we are working to emulate Renesas R-Car X5H SoC, which may also use this configuration. > > The other way to approach this would be to have the > relevant SoC/platform models create a TYPE_OR_IRQ > or gate to wire the interrupts together.
